Fisher 167DAS Series 167DAS-9 Three-Way Switching Valve

Fisher 167DAS Series Three-Way Switching Valve is a compact, precise, easy to maintain, rugged and corrosion-resistant three-way switching valve that can steadily reduce the pressure of gaseous fluids and deliver them to pilot-operated controllers and other pneumatic instruments through 1/4 or 1/2 NPT port connections. It can adapt to temperature environments from -40 to 180°F.

167DAS-9: Ports A and C are 1/2NPT, the air film range is 14 to 20psig when port A or C is used as the inlet, and the air film range is 7 to 20psig when port B is used as the inlet.
